U-shaped development in math: 7-year-olds outperform 9-year-olds on equivalence problems

What is the nature of the association between age (7-11 years) and performance on mathematical equivalence problems (e.g., 7+4+5+7+_)? Many prevailing theories suggest that there should be a positive association. However, change-resistance accounts (e.g., N. M. McNeil & M. W. Alibali, 2005b) predict a U-shaped association. The purpose of the present research was to test these differing predictions. Results from two studies supported a change-resistance account. In the first study (N=87), performance on equivalence problems declined between the ages of 7 and 9 and improved between the ages of 9 and 11. The decrements in performance between the ages of 7 and 9 were then replicated in a second study (N=35). Results suggest that the association between age and performance on equivalence problems is U-shaped.     

Marriage and Family Therapy Graduate Students’ Satisfaction with Training Regarding Religion and Spirituality

Marriage and family therapists are likely to encounter religious or spiritual clients in their career and thus are encouraged to be aware of their clients’ religious and spirituality. This awareness is often fostered within graduate training programs. This study aims to examine graduate students’ incorporation of religion and spirituality in therapy and their satisfaction with the quality and amount of training programs’ adherence to religion and spirituality. A sample of 135 graduate students from American Association for Marriage and Family Therapy accredited programs completed the survey. Findings showed that graduate students with greater levels of religiosity and spirituality were more likely to perceive it important to address religion/spirituality in therapy and to perceive there is a need for religious/spiritual education. When controlling for religious and spiritual orientations, overall regression results revealed that not having a course on religion and spirituality and perceiving a need for religious/spirituality in education predicted lower satisfaction with the amount and quality of current training surrounding these dimensions. Implications demonstrate the need to address religious/spiritual concepts in the curriculum, supervision, and in marriage and family therapy training.     

Middle Class African American Mothers’ Depressive Symptoms Mediate Perceived Discrimination and Reported Child Externalizing Behaviors

Racial discrimination is a chronic stressor in the lives of African Americans. Chronic stress can lead to individual mental and physical health problems, which subsequently can have deleterious effects on family life. The current study explored the effects of perceived discrimination on youth outcomes and examined the potential mediating role of maternal depression. Using data from 189 African American mothers with children aged 7–14 years, maternal perceived discrimination accounted for variance in reported child externalizing behaviors over and beyond that attributable to other stressful life events and socio-demographic variables. Also, maternal depressive symptoms mediated the effect of maternal perceived discrimination on child externalizing behaviors. These results are consistent with the view that mothers’ experience of greater discrimination leads to higher maternal depression which, in turn, leads to greater externalizing behavior among their children. The findings support the need for further exploration of macrosystemic effects that can influence African American youth externalizing behaviors. The results are discussed in terms of the need to include consideration of discrimination in preventive interventions aimed at increasing support systems available to African American mothers.     

Parent-Child Interaction Therapy for ADHD: A Conceptual Overview and Critical Literature Review

ABSTRACT

Attention-Deficit/Hyperactivity Disorder (ADHD), a chronic disorder beginning in childhood, is identifiable and diagnostically valid during the preschool years. Compared to school-aged children, preschoolers have not received as much attention in the literature. Parent-Child Interaction Therapy (PCIT) is an empirically-supported parent training program for young children with disruptive behaviors that may also be effective in treating ADHD. The purpose of the current article was to explore the theoretical rationale for utilizing PCIT with this population and to conduct a literature review of published PCIT treatment outcome studies that measured ADHD symptoms. The literature demonstrates that children with ADHD have been included in PCIT research and evidence suggests that PCIT may be effective for young children with ADHD. However, future research is needed to specifically examine the effects of PCIT on ADHD.     

In-Home Parent-Child Interaction Therapy: Clinical Considerations

ABSTRACT

Parent-Child Interaction Therapy (PCIT) is an empirically-supported behavioral parent training program designed to be administered in a clinic or laboratory-based setting. Recently, an empirical investigation revealed that in-home PCIT produced comparable results as the PCIT trials conducted in more controlled environments (this issue). Administering PCIT in a home setting carries both drawbacks and advantages. This article provides an overview of both the positive and negative clinical aspects of conducting in-home PCIT and presents effective solutions to potential treatment barriers.     

ANS acuity and mathematics ability in preschoolers from low‐income homes: contributions of inhibitory control

Recent findings by Libertus, Feigenson, and Halberda (2011) suggest that there is an association between the acuity of young children's approximate number system (ANS) and their mathematics ability before exposure to instruction in formal schooling. The present study examined the generalizability and validity of these findings in a sample of preschoolers from low‐income homes. Children attending Head Start (N = 103) completed measures to assess ANS acuity, mathematics ability, receptive vocabulary, and inhibitory control. Results showed only a weak association between ANS acuity and mathematics ability that was reduced to non‐significance when controlling for a direct measure of receptive vocabulary. Results also revealed that inhibitory control plays an important role in the relation between ANS acuity and mathematics ability. Specifically, ANS acuity accounted for significant variance in mathematics ability over and above receptive vocabulary, but only for ANS acuity trials in which surface area conflicted with numerosity. Moreover, this association became non‐significant when controlling for inhibitory control. These results suggest that early mathematical experiences prior to formal schooling may influence the strength of the association between ANS acuity and mathematics ability and that inhibitory control may drive that association in young children.     

Prosopagnosia: A face-specific disorder

A follow-up study of a patient, WJ, with a very severe prosopagnosia is reported. After a stroke he became a farmer and acquired a flock of sheep. He learnt to recognize and name many of his sheep, and his performance on tests of recognition memory and paired-associate learning for sheep was significantly better than on comparable tests using human face stimuli. It is concluded that in some instances prosopagnosia can be a face-specific disorder.     

Effects of speech rate on the absolute and relative timing of apraxic and conduction aphasic sentence production

The purpose of this investigation was to provide a constructive replication of the Kent and McNeil (1987, In Phonetic approaches to speech production in aphasia and related disorders. San Diego: College-Hill Press) study of the speech timing characteristics of apraxic and conduction aphasic speakers. Acoustic analysis was used to obtain absolute utterance durations, segment durations, and vowel formant trajectories from utterances produced under control, fast, and slow rate conditions. Segment-to-whole ratios and slope values were calculated. Results support the hypothesis presented by Kent and McNeil (1987) that there is a phonetic-motoric component contributing to the speech patterns of both the apraxic and conduction aphasic speakers sampled. Theories of rate control in normal and disordered speakers are discussed.     

Prebirth and postbirth influence on the relationship between creative ability and recorded mental illness1

Groups of 10 high, 20 above average, and 20 low creative ability subjects were constituted by interjudge agreement from among an adult population who were removed from their biological parents and adopted shortly after birth. The adoptees thus received prebirth influence from their biological relatives and postbirth influence from then: adoptive relatives The rates of recorded mental illness were determined among the adoptees, their biological parents and siblings, and their adoptive parents and siblings Mental illness rates in the adoptees were positively and significantly related to their creative ability level, substantiating the hypothesized relationship between creative ability and mental illness. The mental illness rates of the biological parents were positively and significantly related to the creative ability level of the adoptees. Mental illness rates among the adoptive parents and the adoptive and biological siblings were independent of the adoptees’ creative ability level. The data were interpreted as evidence for the influence of prebirth factors on the relationship between creative ability and mental illness No evidence of family-related postbirth influence was found An evaluation of mental illness rates among uncooperative (nonresponding) potential subjects and their relatives suggested that noncooperation by these adoptees produced a dampening effect on the results of the study.
